Coefficient Quarter-Zip Hoody - Men's

About this find

Want a layer that handles a long day outdoors? The Black Diamond Coefficient Quarter-Zip Hoody is made from Polartec Power Dry fleece, a blend of 51% polyester, 36% nylon and 13% elastane, with a gridded interior that helps it wick moisture and stay breathable. Its quarter-length zipper lets you adjust temperature as you warm up or cool down, and the under-the-helmet hood adds coverage when you need it.

The slim cut fits comfortably under a shell jacket, so you can layer without bulk. Lightweight stretch cuffs with integrated thumbholes keep your sleeves in place, and a zippered chest pocket gives small items a secure spot. At about 9 ounces, it stashes easily in your pack when you don't need it.

Try it under a windbreaker on a chilly morning hike, or wear it alone over a short-sleeve tech tee when the weather is mild. Pair it with trail pants or jeans for a practical, easy look. The hip-length back offers good coverage while you move.
